Title: Improvements relating to ramming devices of firearms
IPC: F41A9/42
Filed: 1958-05-28
Abstract: 833,860. Ramming mechanisms. BOFORS A. B. May 28, 1958 [June 20, 1957], No. 17008/58. Class 92 An automatic firearm having a hydropneumatically operated rammer whose lug engages the flange of a cartridge is characterized by a choking device that can be closed or opened between the hydraulic cylinder 3 and a closed air vessel 7 (Fig. 1, not shown), connected to it and has a feeler member that closes the device when no round is in the ramming position. The lug 1 is in the form of a spring catch on the outer end of the piston rod 2 which has guided rollers 8. The hydraulic cylinder piston 4 is pushed back on recoil of the gun and is held in the cocked position by a latch 11 on a pivoted lever 12 which is held down by an arm 14 that can be rotated to free the piston and cause it to ram a round 16. A hinged plate 17 is unsupported when no round is present; permitting a linkage 18-21-22 to rotate a strangler-flap 24 into the outlet orifice 6 of the accumulator 5 so that the piston speed will be reduced and the use of a buffer stop at the end of its travel is unnecessary. The air above the fluid in the accumulator 5 is contained in a rubber bag (Fig. 1. not shown).

Title: Improvements in and relating to heating and deaerating liquids
IPC: B01D19/00
Filed: 1920-06-24
Abstract: 173,534. Morison, D. B. June 24, 1920. Heating liquids.-To heat and de-aerate liquids such as boiler feed-water, the liquid is passed into a pipe-like structure, and into the lower end of the column are upwardly injected films of steam at a velocity and pressure, such as will impart to the liquid an upward velocity approximating to that of a bubble of air rising freely through the liquid, whereby there is induced in the column of liquid stream-lines of upward unconfused flow. The desired conditions are attained by locating the nozzle through which the steam is introduced, at the correct depth beneath the surface of the liquid ; the position can be determined according to the values of the pressure and the velocity of the steam, but in practice a satisfactory result is obtained by lowering the nozzle until a position is reached where the upheaval of the surface ceases. The efficiency of the treatment is increased by withdrawing a portion of the treated and hot liquid and mixing it with the untreated and relatively cold liquid. The treatment is carried out in apparatus similar to that described in Specifications 11690/10 and 19564/11, the steam being introduced through radial slits in nozzles 2 located at the lower ends of and extending completely across a pipe or pipes 3, Figs. 1 and 5; the separated air collects in a hood 4 and is discharged through a pipe 5, and the de-aerated and heated water flows downwardly through an extension 4a and then upwardly to a discharge pipe 6. In Fig. 5, some of the de-aerated and hot water is returned through a pipe 7 to the inlet end of the pipes 3 for re-treatment; and in this construction the liberated air escapes through a condenser 8, condensed water being returned through a pipe 9. The 'de-aerator may be placed at a considerable height above the feed-pump, in which case the temperature of the water may reach 212‹ F. or higher, a loaded valve being then provided for the escape of air from the de-aerator.

Title: Improvements in and relating to weighing apparatus

Abstract: 329,523. Fitzpatrick, H. D., (Naamlooze Vennootschap Maatschappij tot Vervaardiging van Snijmachines Volgens van Berkel's Patent en van Andere Werktuigen). June 5, 1929. Pendulum-weight apparatus; beams.-In a weighing-apparatus the tare beam for supplementary weights is freely suspended by a member depending from a fixed part of the apparatus, and is also freely suspended by a member or members depending from a part which, whilst being movable by the weighing mechanism, is held against 'lateral movement relative to the fixed part. The tare beam or steelyard 1 has a fixed counterweight 2 and a sliding weight 3 or a hanger 4 with supplementary weights 5 or a scale pan 6 or any of these alternatives in combination. The pivot D of the beam is suspended from a fixed point A by a link 8. A second parallel link 10 is pivoted at one end C to the beam and, at the other end B, is pivoted to a. push or pull rod 9 connected to the weighing and indicating mechanisms. The rod 9 is prevented from moving laterally, and thus if the apparatus is placed slightly out of level, the parallel links 8, 10 and the beam swing, for example, into the positions shown by dotted lines and the proportions of the turning moments acting on the beam remain unaltered and the accuracy of the weight indications remains unaffected. In a modification, the pivot B, instead of being mounted directly on the rod 9, is suspended from the rod by an additional link, and the pivots A, B are connected by a further link.

Abstract: 121,168. Johnson, L., and Roberts, J. T. Dec. 1, 1917. Magnetos, driving. -In trip mechanism for ignition magnetos in which a piece moving longitudinally against a spring in the driving-member co-acts with a camsurface on the driven member, the holding and releasing device consists of levers abutting against a fixed stop and disengaged therefrom by cams. On a piece B<1> attached to the engine shaft B slides a collar B<2> carrying a roller B<3> which runs on a cam-surface A<2> formed on a member A<1> attached to the magneto spindle A. The collar B<2>, with its roller B<3>, is pressed against the camsurface A<2> by a spindle C. To the piece A<1> are pivoted levers D, the inner ends of which engage with a fixed stop E and hold the magneto shaft still, until a cam B<4> on the piece B<1> moves the levers so as to release the piece A<1>, which is then rotated rapidly by the action of the spring C and the cam A<2>. Springs F, attached to the piece B<1> and striking against the piece A', serve as buffer springs. When the engine is running quickly, the levers D are kept out of the way of the stop E by centrifugal action. To prevent the device from operating when the machine is running slowly, a guard E<3> is arranged so as to move the levers out of the way of the stop, but so that the levers have time to fall by gravity into the engaging position when the machine is being cranked round.

Title: Improved can coating compositions and methods of making them
Filed: 1956-06-12
Abstract: A can-coating composition comprises from 70-90 parts by weight of a liquid polymeric drying oil obtained by blowing a butadiene polymer or a butadiene-styrene copolymer with air or oxygen, and 30-10 parts of a melamineformaldehyde condensation resin. Preferably the copolymer is obtained by copolymerizing 50-100 parts of butadiene and 50-0 parts of styrene in the presence of a finely divided alkali metal catalyst such as lithium, sodium, potassium, caesium, or rubidium, using as a diluent naphtha, straight run mineral spirits, butane, pentane, benzene, toluene, xylene, cyclohexane, butenes or pentenes.  In addition, promoters such as dioxane-1,4, the diethyl ether of ethylene glycol and diethylene glycol; diether acetal, vinyl isobutyl ether, dihydropyrone and ethylol; isopropanol, isobutanol, isopentanol, secondary butanol and tertiary butanol may be added, and destruction of the catalyst at the end accomplished by adding a moderate excess of an anhydrous C1 to C5 fatty acid such as formic, acetic or pentanoic or sulphuric acid.  The stripped polymer oil may then be dissolved in an aromatic solvent such as benzene, toluene, xylene, hemi-mellitine, pseudocumene, mesitylene, propyl benzene, cymene, cumene, ethyl toluene and methyl-ethyl benzene and the solution contacted with oxygen or air at 70-300 DEG  F. for 1 hour to 4 days.  Catalysts for the oxidation include organic salts such as naphthenates, or octoates of cobalt, lead, iron and manganese; and benzoyl peroxide.  Oxidation is continued until 0.05 to 20 per cent of oxygen is absorbed.  The melamine resin is preferably that obtained by reacting 3 molecules of formaldehyde with 1 molecule of melamine.  Preferably 20 per cent of melamine formaldehyde resin is used in the composition.
